The Giants' series against the Rockies continues with Saturday's 6:05 p.m. PT home matchup, when Madison Bumgarner (5-6, 3.30 ERA) will try to rebound from a pair of poor starts that resulted in 11 earned runs across 11 innings of work. The Rockies knocked him around for seven runs (six earned) in their last meeting on Sept. 3 at Coors Field. Colorado will counter with righty German Marquez (12-9, 3.94), who has racked up at least 11 strikeouts in each of his past three outings.
